(01. 128-334) The presentinvention relates to asuturing and ligating instrument of the general type forming the subject matter of my :co-jending application which bears Serial No. 514,223, filed on February 7, 1931, and upon which this invention constitutes an improvement. c

An important object of the present invention is to provide, in a manner as hereinafter set forth,- a suturing and. ligating instrument embodying a novel construction and arrangement of 1 parts through the medium ofwhich a ligaturegmay benexpeditiously looped and tied; x s

Other, objectsof the invention are to providea suturing and ligating instrument of the character described which will be simple in construetion; strong, durable, efficient andreliable in use andiwhich may be manufactured at low cost. :1

All of the foregoing and stillJfurthergobjects andadvantages of the' invention will become apparent from a study of the following specification, taken in connection with :the accompanying drawings -.wherein like characters of reference designate corresponding parts throughout? the several views; and wherein:-

Eyes 4 constituting handles are formed integrally with one end of the levers 2 and=3. At its other, end the lever 2 is turned substantially at right angles toward the corresponding end of the lever 3 in a manner to provide a needle 5 which-terminates, at its free end, in ahook 6. A 'substantially tubular housing 'T is slidablymounted on the needle 5 and has formed integrally therewith an extension 8 with which the freerend portion ofa spring" 9 is engaged in a manner to yieldingly urge the: housing 7 toward the free end of the needle 5; r At its other end portion the spring 9 is secured to an intermediate portion of the-lever 2, asat 10'.

The outer end of the stripping bar 1 'isprovided with a' substantially right" angularly disposedportion 11' which-extends toward the bar 2 andwhich terminatesina longitudinally extending offsetportion lzhaving formed integral:

ly therewith a'stripping-eye 13through which; the tubular housing'l'and the needle 5 are operable.v The angular portion 11 of the stripping bar 1 is providedwith' an opening inwhi'ch :is slidably disposed a'tubular sleeve 14 having its end portions flared, as best seen in Figure 5': of .the The purpose of the -sleevel4 willbe presently set forth. The stripping bar 1 is further provided with a guide l5through which is slidable a rod lfi-"hzvinga loop 17 constituting a' handi'e on its inner end. The outer end of-the'roduld has thereona hook 18 for tightening the ligature when the instrumentisin use: V

On the side thereof which is adjacent the lever 2, the outer end portionof the lever 3'has formed therein an elongated notch or recess 19 with the outer-end portion of whiohaslot'20 in the lever 3 communicates; At an intermediate point the lever 3 is further'provided, outwardly of the pivot pin21; with anotherslot 22. A passage 23 establishes communication between the slot 22 and the innerendof the elongated 'notchorreoess shifting said latching bar outwardly. The slot 22 in the lever 3 is for the reecption of the cam 28.

The reference numeral 29 designates a resil- 5 ient hook which is mounted on an inner portion intermediate portion of the ligature 30 is tied in a I 1 loop 31 around the sleeve 14. One end portion of the ligature is then looped around the housing 7, as at 32, and threaded through the sleeve 14 and engaged with the hook 18, as at 33. The

sleeve 14 is supported in its uppermost position when the ligature is tied thereto. The other end portion 34 of the ligature is inserted transversely through the enlarged upper portion of the 81011-7.

gated slot or recess 19 in the lever. 3.

With the ligature left mounted on the instrument, said ligature may be looped and tied to the tissue 35 by swinging the outer end of the lever 3 toward the corresponding ends of the stripping bar 1 and the lever 2. This will cause the needle 5 to pass through the outer portion of the slot or.recess 19 and through the slot 20 of the lever 3, said lever 3 engaging the housing '7 and sliding said housing away from the free end of the needle 5 against the tension of the spring 9;; As the needle 5 enters the slot 20, the cam 28 enters the slot 22 and engages the bar 24, moving said bar outwardly. It will be noted that the end portion 34 of the ligature 30 is engaged on the outer end of the bar 24. The bar 24 moves the ligature 30 into the path or the hook 6 of the needle when said needle is withdrawn from the slot 20. In this manner the end portion 34 of the ligature is engaged by the needle 5 and drawn into the housing '1 when the levers 2 and 3 are swung apart. Of course, this removes the ligature 30 from the slot or recess 19in the lever 3. The slot 2'7 in the plate. 25 is for the passage of the needle 5.

When the levers are in the position shown in Figure 5 of the drawings, the, hook 29 engages the lever 3 and in this manner the stripping bar 1 and said lever 3 are secured together; Thus,

" the stripping bar 1' having the eye 13 thereon and the lever 3 remain relatively stationary when the needle 5 is withdrawn from the slot 20 carrying with it the end portion 34 of the ligature 30. Movement of the-lever 2 away from the locked together lever 3 and the stripping bar 1 withdraws the housing 1 from the eye 13 with the result that the loop 32 of the ligature 30 is stripped from-the housing 7 and now encircles the end portion 34 of said ligature which has been drawn into the housing 7 by the needle 5. It may, perhaps be more correct to say that as the lever 2 is swung away'from the lever 3 and the stripping bar 1 the spring 9 moves the housing 7 toward the free end of the needle 5 for engagement over the end portion 34 of the ligature 30. I

The sleeve 14 is of a diameter to frictionally engage the ligature 30 but to permit sliding movement of said ligature ,therethrough when force is exerted thereon. After the loop 32 has been stripped from the housing '7 by the stripping eye 13, .the rod 16 is slid inwardly and, through the medium of the hook 18,.draws the end-portion 33 of theligature inwardly through the sleeve 14 in a manner to restrict or reduce the loop 32 and to slide thesleeve 14 inwardly through the angular portion 11 of the stripping bar 1 by reason of the frictional contact of the ligature with the sleeve. This inward movement of the sleeve 14 strips the loop 31 of the ligature therefrom by engagement of said loop 31 with the outer face of the angular portion 11. Thus, loops and slip knots have been formed which, by continued inward movement of the rod 16, will tighten and tie the ligature about the tissue. It will be noted that after the loop 31 is stripped from the sleeve 14, the end portion 33 of the ligature passes through said loop 31.

It is believed that the many advantages of a suturing andligating instrument in accordance with the present invention will be readily understood, and although the preferred embodiment of the invention is as illustrated and described, it is to be understood that changes in the details ,of construction and in the combination and arrangement of parts may be resorted to which will fall within the scope of the invention as claimed.
